04 E450 with 6.0
just finished installing turbo back on engine (unison ring rusted to housing) and took out for a test. Runs much better but after getting it up to temp. I dropped the hammer from about 35-40 mph and held it. At about 70 I had a very loud boom and a wave of air hit me (engine cover off). The hose that is connected to the turbo outlet side blew off with what seemed a lot of pressure. I thought the clamp was tight. Is there any way the system could have been over pressurized to blow the hose off. I am going to retry tomorrow. I can't see how the cooler could be clogged since only air goes thru it, but when it blew it had what seemed like a lot of pressure. Truck has 30,000 miles on it. Any input. Thanks

Clean it off really good the CAC Boot and take some Wifes Hairspray spray it good and Clamp it
They get Oily and slide off under pressure
Do you have a way to monitor BOOST??
28psi is all you want to see
Do you see more than 28psi Boost???????????

It can't be stressed enough, make sure all of the oil/grease is off the CAC tubes & boots; I've found that brake cleaner will get 'em clean. I want to say you need to torque the clamps to 20 Ft/Ibs; but if you get them "good & tight" after getting the tubes/boots clean you shouldn't blow them off again.
Since you just reinstalled the turbo...I'm going to assume you cleaned the vanes and applied anti-seize (1600F) before putting everything together. If so, I doubt your overboosting the boots.
